Recent trial results suggest that the consumption of a low glycemic index (GI) diet is beneficial in the prevention of high blood glucose levels. Identifying active hypoglycemic substances in ordinary foods could be a significant benefit to the management of blood glucose. It has been hypothesized that noodles with Bombyx mori powder are a low GI food. We evaluated GI and changes in postprandial glucose levels following consumption of those noodles and compared them with those following consumption of plain wheat flour noodles (control) and glucose (reference) in healthy subjects. Thirteen males (age: 34.2±4.5 years, body mass index: 23.2±1.1 kg/m²) consumed 75 g carbohydrate portions of glucose and the 2 kinds of noodle after an overnight fast. Capillary blood was measured at time 0 (fasting), 15, 30, 45, 60, 90, 120, and 180 min from the start of each food intake. The GI values were calculated by taking the ratio of the incremental area under the blood glucose response curve (IAUC) for the noodles and glucose. There was a significant difference in postprandial glucose concentrations at 30 and 45 min between the control noodles and the noodles with Bombyx mori powder: the IAUC and GI for the noodles with Bombyx mori powder were significantly lower than those for glucose and plain wheat flour noodles. The wheat flour noodles with Bombyx mori powder could help prevent an increase in postprandial glucose response and possibly provide an alternative to other carbohydrate staple foods for glycemic management.

Compliance effect for real time multi-body vehicle dynamics model has been considered using quasi-static analysis method. In this method, hard point locations of the suspension subsystem are changed according to the deformation of bush due to joint reaction force. Real time multi-body vehicle model is established using the subsystem synthesis method which is based on recursive formulation. Joint reaction forces are computed by using non-recursive formulation. The proposed method has been validated with 1/4 car simulation of multilink suspension model by comparing with ADAMS compliance model. The proposed method increase very little computation amounts. Thus, it is well suited for real time model.

According to 2005 national census and the statistical analysis of traffic accident from nation policy report, 65 year older population and fatalities are on the rapid increase. Especially elderly driver and passengers have a disproportionately higher crash involvement rate and commonly sustain more severe injuries than the other generation. The current frontal impact regulation of Korean safety standard is based on the FMVSS208 to protect the motor vehicle occupant in the event of frontal crash type accidents. The injury criteria utilized in the regulation is based on Hybrid 50%ile dummy. In this study, the thorax injury criteria and the biomechanical chest impact response(F-D corridor) for Korean elderly were derived from the scaling method that takes into account the differences in size and material properties of the rib bone between adults and elderly. Also the Korean elderly Hybrid III simulation model was verified using the chest impact response scaled from response requirements of the Hybrid III 50%ile dummy.

An approximate function approach has been developed using the subsystem synthesis method for real-time multibody vehicle dynamics models. In this approach, instead of solving loop closure constraint equations of the suspension linkage, approximate functions are used. The approximate function represents the functional relationship between dependent coordinates and independent coordinates of the suspension subsystem. This kinematic relationship is also included in the suspension subsystem equations of motion. Different order of polynomial functions are tried to find out the best candidate functions. The proposed method is also compared with generalized coordinate partitioning method and constraint stabilization method to verify its accuracy and efficiency in real-time.
